Pregnant??

Okay so a little back story. About a week or two before my last period (last period ended about a week ago, and started about 2 weeks ago, I only had it for about 6 days) I had unprotected sex (two days in a row) BUT we only went for a few mintes and he didn’t cum, but obviously there was precum. For that period it was pretty heavy from being on birth control (when I had sex I was on medication that made my pills Not work) I also had sex about a week ago the day my period ended and the condom broke but he put another one on (and I’m pretty sure my bc was working again by then) anyway now my breasts are big(I’m pretty sure they are swollen by they don’t really hurt that bad like when I’m on my period) and I was nauseous a bit for liek a week (stopped like two days ago) and I feel liek I look pregnant even tho it’s to early to tell, I think I’m just out of shape lol. But is there any way I could be pregnant? Like front the pre cum or condom breaking? I’m going to take a test later today but Ive even worried for about a week. But since i got my period i wasn’t to scared (but then again you can still get a peorod while pregnant) anyway I have no idea where to post this so I’m gonna post it liek three times in different groups for different responses lol sorry if this gets annoying.( also I am really hopin a doctor or gyno will reply to this🙏🏽)
